Another view of the south lobe of the June 27th flow, which plunged into a deep ground crack last week (this spot is visible at the right side of the photograph). This wide view, looking west, also shows another deep crack nearby, a short distance to the south of the active flows (which are producing the smoke plumes).

The new volcanic-gas monitoring station installed at Mount St. Helens consists of weather monitoring equipment and sensors for measuring the concentrations of water vapor (H2O), carbon dioxide (CO2), sulfur dioxide (SO2), and hydrogen sulfide (H2S) in volcanic gas plumes.

Pu‘u ‘Ō‘ō crater remains partly obscured by thick fume. In particular, the northeastern portion of the crater (bottom left part of image) has recently been entirely obscured to the naked eye, but the thermal camera provides a clear view through the fume, revealing a small lava pond.

The leading edge of the June 27th lava flow plunged into a deep crack on Kīlauea's East Rift Zone last week, and lava within the crack remained hidden for several days. Over the past day, lava returned to the surface at a point slightly farther along the crack, creating a small island of lava surrounded by thick forest.

Map showing the June 27th flow in Kīlauea's East Rift Zone as of August 25, 2014. The area of the flow as mapped on August 22 is shown in pink, while widening and advancement of the flow as of August 25 is shown in red. The brown line marks the ground crack that channeled lava to the east, where it emerged to form a new pad of lava over the past couple of days.

A view of the small pad of lava that has emerged from the crack over the past day. The lava pad was about 800 m (0.5 miles) long, and was about 1.3 km (0.8 miles) east of the point where lava plunged into the crack.

Another view of the isolated pad of lava that has emerged from the crack. This view is towards the east, along the East Rift Zone. The spot at which lava flowed into the crack is to the west, out of view beyond the bottom of the photograph.

Map showing the June 27th flow in Kīlauea's East Rift Zone as of August 22, 2014. The area of the flow as mapped on August 12 is shown in pink, while widening and advancement of the flow as of August 22 is shown in red. The heavy brown line marks the extent of steaming along a ground crack into which lava is flowing.

Pu‘u ‘Ō‘ō crater remains partly obscured by thick fume. The thermal camera today revealed that several lava ponds persist in their usual locations in the northeast and southeast portions of the crater floor.

Lava from June 27 breakout flowing into deep ground crack along Kīlauea's East Rift Zone, Pu‘u ‘Ō‘ō, Hawai‘i.

A closer look at one of the steam sources. The crack from which steam is issuing is not visible through the thick vegetation.

This image shows a broad overview of activity at the front of the June 27th lava flow. Steaming in the lower-center portion of the photograph issues from a crack on the East Rift Zone. A portion of the lava flow has entered this crack, and the steaming extends out 1.4 km (0.9 miles) from the visible flow margin at the surface.

Looking west, this photo shows the far end of the steaming that extends out beyond the visible flow margin at the surface.

A view looking east, near the front of the southern lobe that has entered the crack. Lava is inferred to be present in the deep crack beyond the visible margin of the flow, based on the line of steam sources as well as a vigorous cascade of lava seen in a skylight in the bottom portion of the photo.

Preview image for video: shows the southern front of the June 27th lava flow from Pu‘u ‘Ō‘ō. Lava here has flowed into a deep crack on Kīlauea's East Rift Zone. The line of steam extending out from the visible flow margin at the surface is inferred to be caused by lava deep within the crack.

A closer look at the lava stream plunging into the crack. The lava is fed from the vent on Pu‘u ‘Ō‘ō via a lava tube.

North of where lava is entering the crack, another lobe is pushing through thick forest, triggering small brush fires. The source of the smoke marks the front of this lobe, and Pu‘u ‘Ō‘ō can be seen just above this spot.

The surface flows active at the front of the June 27 lava flow are fed from lava flowing through a lava tube. This collapse of a portion of the roof has produced a skylight, and a direct view of the fluid lava stream several meters (yards) beneath the surface.

The June 27 lava flow remains active as a narrow lobe pushing through thick forest northeast of Pu‘u ‘Ō‘ō, triggering small brush fires. This view is to the east, with the forested cone of Heiheiahulu partly obscured by the smoke plume from this angle. The flow front today was 8.7 km (5.4 miles) northeast of the vent on Pu‘u ‘Ō‘ō.
